Hi,
I hope this information helps you decide what to do. I'd really weigh how badly you want a right side mirror. While the cost in money isn't high, the cost in aggravation and possible finish damage is.
I suspect that you are not in the USA but here is some information on parts, both the mirror and the pin ....

Here is a forum on hinge removal with photos of the proper tool as well as suggestions by others about how to do it.
